Redemption supposes taking us out of one condition, and putting us into another. In Christ's death we get two questions—God's glory and our sins. Redemption is eternal, but not universal. We get the blessings of the new covenant, but there is no covenant with us; the letter of it is for Israel.
There is universal purchase but
not universal redemption. The believer is the only one who owns the purchase, and acts upon it. Everyone may come as to the presentation of the gospel; but this does not interfere with God's sovereignty. Men will be judged for not believing the gospel, and for sins.
